ELUTION CARBON REACTIVATION 4444 Introduction During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption
The Gold Cyanidation Process. The gold cyanidation process is a series of steps that vary depending on the characteristics of the deposit and the type of mine. Although not always the case, this process typically begins with mined gold ore being crushed and ground in order to make the gold .
Parameters affecting gold elution using the AARL process are reviewed and critically analyzed in an attempt to optimise metallurgical efficiency and minimise costs in both current and future carbon adsorption operations. Such factors as acid washing, column geometry, elution temperatures and pretreatment reagents are discussed together with eluant water quality and eluate flowrates.
The absorptive properties of activated carbon are due to the microporous structure of each grain resulting into large surface area per unit column of carbon. In the gold industry, activated carbon is utilized in CIP/ CIL process to transfer dissolved gold from cyanide leached slurry to elution column where gold is desorbed from the carbon.
The ZADRA system is another elution process where gold that is adsorbed on to activated carbon is desorbed from the carbon by a reversal of the adsorption kinetics.
heated at elevated temperatures in the presence of steam to create activated carbon. In gold recovery applications, activated carbon manufactured by Thermal activation is used. This process will be discussed in more detail. There are a number of steps in the production of .
Operation of the electrowinning process differs depending on the elution procedure that is used. In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (<100 g/t) to be reactivated and returned to ...
The manual is all about VAT Leaching Technology which is a low cost technology for recovery of gold from fresh ore or from tails left from previous CIL process and from Small Scale Miners.

ELUTION COLUMNS. Among the major stainless steel products that STEGEL is provisioned to manufacture are elution columns, which are used for gold recovery. The use of elution columns in gold recovery is a costeffective method of recovering gold from the sediment in mine dumps and other areas in which gold particles reside.

sent to the carbon columns, CIC401, via Stream 29. Gold is adsorbed onto the activated carbon. The filtrate is then sent to the elution vessel, V401, where the elution process begins. The gold is eluted into a water solution from the carbon by the AmericanAnglo Research Laboratories (AARL) method, leaving the barren carbon behind. Figure 5

In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ionexchange resins to remove captured ions. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an adsorbent in a liquid chromatography column ...

Elution of AM2B resin is similar to that of Minix; but a longer elution time seems to be required (Bolinsky and Shirley, 1996).The process includes a series of elutions, contacting the loaded resin with different solutions. The elution flowsheet differs from plant to plant, and some of the steps described below are optional.
